Refer to the figures.
Figure 1
Figure 2
You are evaluating three snail species to determine their overall threat as invasive species to an area. You bring several individuals of each species into your lab to test their tolerance of a range of abiotic and biotic factors. Figure 1 shows how the three snail species respond to differences in average temperature and Figure 2 shows the number of prey and parasite species for each of the species in the new areas, along with how competitive each potential invasive species will be in the new community (higher numbers indicate that the species will be a more successful competitor).
-Based solely on species-level tolerances of biotic factors (Figure 2), which snail species pose(s) the least threat as an invasive species in the new area, based on the three types of data collected, and why? Which species might be most affected by biotic resistance? How would the presence or absence of predators impact the ability of the potential invasive species to compete with native species?
